ARM: OMAP1: clock: Fix debugfs_create_*() usage

[ Upstream commit 8cbbf1745dcde7ba7e423dc70619d223de90fd43 ]

When exposing data access through debugfs, the correct
debugfs_create_*() functions must be used, depending on data type.

Remove all casts from data pointers passed to debugfs_create_*()
functions, as such casts prevent the compiler from flagging bugs.

Correct all wrong usage:
  - clk.rate is unsigned long, not u32,
  - clk.flags is u8, not u32, which exposed the successive
    clk.rate_offset and clk.src_offset fields.
